Bosch Dishwasher Error Code 209 (Read This First)

Bosch dishwashers usually come with a screen display that shows different error codes. These dishwasher error codes often result from a faulty unit in the washer.

The 209 error code is not quite an error code in Bosch washers. Instead, it may display because of a malfunction in your Bosch washers.

Let’s find out what this code means and take steps to resolve it.

Your Bosch dishwasher often displays the 209 error code due to a faulty main control board. This error also displays on the screen when the water inlet valve is in a critical condition, or there are sud build-ups in the washer. This washer error code usually appears due to a stuck keypad problem and an unresponsive keypad.

Bosch Dishwasher Flashing 209? 

The 209 error display, in most cases, signifies a faulty control board. The control unit regulates the functions of the dishwasher, especially the display screen.

A defective control board might delay the screen display causing the 209 display on the screen to get stuck.

When you encounter a dishwasher error, the first thing to do is to reboot the machine. By restarting your washer, you can verify the source of the error code if the issue persists.

For example, it might be a damaged component in your Bosch dishwasher if it continues.

According to the Bosch dishwasher brand, the washer error codes are E1, E2, E3, E4, E5, E6, E9, and quite a few other error codes.

However, among these error codes, there is no 209 error code. This means that the display is a timer display, and the machine gets stuck at this display.

The 209 error display is due to unusual internal component damage.

Depending on the cycle you are using to wash, 2:09 might be the cycle’s time to complete.

Unfortunately, the timer probably got stuck during the wash cycle and will need to be reset if it is not in poor condition.

If you tried resetting your Bosch dishwasher error code and the fault persisted, you should check the internal parts for damages.

Why Does My Bosch Dishwasher Flash 209?

There are various reasons your Bosch dishwasher keeps displaying the 209 error code. Most of the reasons that could make your washer display the 209 error code are:

#1. Stuck or Faulty Timer

The timer controls most functions in the dishwasher. It comprises some electrical terminals that control the timer motor.

The timer motor keeps the timer working when the washer is running.

If the timer is faulty, the timer might get stuck. Test the timer with a multimeter before replacing it.

#2. Damaged Water Inlet Valve

The inlet valve controls the water flowing into the dishwasher during the wash cycle. If the wash cycle gets stuck at 209 during the wash cycle, you have a damaged water inlet valve.

Before testing the water valve for faults, check the water hoses for clogs that might restrict water flow. Also, check the inlet screen for filth and debris.

If these are in good condition, test the water inlet valve for continuity with a multimeter.

#3. Built-up Suds in Washer

The dishwasher error code 209 is also due to excessive suds in the dishwasher.

Suds accumulate in your dishwasher because you used the wrong detergent or sometimes too much detergent during a wash cycle.

The washer responds to this sudsy situation by adding a rinse and drain cycle to reduce the suds in the washer.

If this doesn’t work, your machine will resort to pausing the cycle during a wash. Unfortunately, this pause could be for a long time.  

#4. Faulty Control Board

The control board is the control unit in your dishwasher. It regulates all the functions of the dishwasher.

After checking for all mentioned faults, and none seem to be amiss, your control board is at fault. 

Sometimes, resetting your dishwasher gets the control board back to its normal functions if the error occurred during a sudden power outage.

It also erases all error codes, but the control board needs a new replacement for the dishwasher to run efficiently if that doesn’t work. 

How To Fix Error Code 209?

Resolving the 209 washer error code is usually straightforward if you know the source of the issue.

These are some different ways to get your dishwasher unstuck from the 209 error code:

#1. Reset Dishwasher

Resetting your dishwasher is the first step to clearing your dishwasher error codes. It is an easy repair procedure.

Though it doesn’t always work, it won’t hurt to try it. To reset your Bosch dishwasher:

  • Turn off the power outlet connected to the dishwasher before resetting the dishwasher.
  • Turn off the child lock feature. If it is on, you cannot change or reset the dishwasher.
  • Hold the ‘<’ button for five seconds to turn it off.
  • Hold the On and Off keypad for ten seconds. It would reset your Bosch dishwasher.

Some Bosch models have a different reset method. Here’s another way of resetting your Bosch dishwasher:

  • Hold the Start-Pause keypad for five seconds, or until the timer display reads 0:00.
  • Shut the dishwasher door and wait for the water to drain out from the washer.
  • Turn on the On-Off button.

#2. Replace Faulty Timer

Before replacing the timer, ensure to test the timer motor with a multimeter. To test the timer motor for damages:

  • Switch off the dishwasher power outlet.
  • Open the control panel, locate the timer and disconnect it from the washer.
  • Connect your multimeter probes to the ends that regulate the timer motor.
  • If your multimeter reads zero or close to zero, your timer motor is in good condition.
  • If not, you need to replace the timer.

#3. Replace Water Inlet Valve

Before replacing your inlet valve, test it for faults. To test your inlet valve:

  • First, unplug the dishwasher from the power outlet and turn off the water supply.
  • Next, detach the wires from the inlet valve with pliers.
  • Attach a multimeter to the ends of the wires. The multimeter should read anything but infinity. If it reads infinity, then the solenoid in the valve is in bad condition.
  • If it reads infinity, check the valve for food particles. Clean out the valve if there is debris.
  • If the inlet valve is bad, it needs replacement.

#4. Clean Out Suds in Washer

To clean out the suds in your dishwasher, select a wash cycle and pour one cup of white vinegar into the dishwasher.

Let the wash cycle run for four minutes. It will gradually reduce the suds.  

#5. Change the Control Board

If the control board is damaged, you will need to replace it. A faulty control board could also cause other problems in your dishwasher if you do not replace it on time.

Once you fix the control board unit, your dishwasher will run, and a new one. 


Bosch Dishwashers are quite durable, but errors are not inevitable in machines in the long run.

For example, the 209 washer error code often occurs due to a faulty control board or a damaged water inlet valve.

Resetting your dishwasher should be the first step to fixing the error code. Employ the services of a professional if you cannot replace the faulty components yourself.
